    Millermatic 255 with pulse!

    Miller is at it again. Apparently this is new and I'm not sure it is available or soon to be.

    Front looks like their new Multimatic 220 AC/DC but it is a MIG with a higher duty cycle. I guess it could do what a 252 would, haven't compared the specs in depth.
    Edit: Ok when you open the link a window pops up that says "comming soon".

    with the exception of the pulse feature, and the fact that it is an inverter (the 252 is a transformer machine), it has virtually the same specs as the 252, with one exception. The 252 always boasted about its max output being at 28 volts, and how that was the highest in the industry or something. The 255 hits the output at 25.5 volts. But man I am loving the Bernard gun the 255 comes with.

    The spec sheet claims 20-350 amp output. What happened to proofreading prior to publication?

    The duty cycle chart, on the spec sheet, is showing a 10% duty cycle @ 350 amps.

    I really don't know how big a deal the voltage numbers are? Maybe the inverter vs. transformer has something to do with that. Does appear to match up to the 252. And previously if you wanted a machine with a pulse you went from the 252 to the 350's. I am going to look for reviews or what ever users have to say. This one has me thinking about a possible upgrade with a push pull set up with aluminum if that would work.

    Yeah not sure either. The only reason I would think it is a big deal is if you need that voltage to run certain wires (thinking of dual shield or metal core here) some of those wires need more than 26 volts to hit the higher wire feed speeds.

    In the manual, the rated output for 40% duty cycle is 27 volts @ 260 amps.

    "Coming soon". I hope it doesn't take a year-plus to get them out there. Every time I consider a change or upgrade they (not just Miller) make you wonder if you should wait.

    Couldn't find anything from Sema about the 255,and nothing on you tube. Not sure Miller will have a demo on display at the Fabtech show either. They did follow through with the 220 AC/DC multi-process fairly quick though so who knows when "coming soon" is.

    I am standing in front of the machine right now at Fabtech. It has fan on demand and will be available in January.

    They have a mult-process DC tig model 255 coming out in January as well

    COOL! Is the 255 just on display or is it a demo?
